A bag consists of 4 different colored marbles. The probability of drawing each is as follows:

P (Blue)=. 4 P (Red)= .2 P (Purple)= .3 P (Black)= .1

You draw a marble out of the bag and then replace it.

What is the probability that you draw:

a. A red marble first and a blue marble second?

**.2 * .4 = 8%**

b. A black marble first and a purple marble second?

**.1 * .3 = 3%**

c. A red or blue marble?

**.2 + .4 = 60%**

d. A gray marble?

**0**

**Are these answers correct?**
